Octyltin mercaptide

In Figure 3.3.5, the dehydrochlorination curves for a di-n-octyltin mercaptide stabilizer are shown. It can be seen that the induction period increases almost linearly with the stabilizer concentration. As a first approximation, the length of the induction period may also be considered as a measure of the binding capacity of the stabiizer for hydrogen chloride. Furthermore, the gradient of the curves decreases with increasing concentration of the stabilizer, and this can be seen as an indication that the conversion products have a favorable effect on the heat stability of the PVC.

Thermal stabilizer used in this formulation was intentionally developed for the process. It gives excellent thermal stability (stability time of 26.4 min compared with 17.2 min for octyltin mercaptide/maleate which is commonly used for such applications).

Organotin Stabilizer n Any of an important class of stabilizers for PVC, notable for their high efficiency, compatibility, and imparting of clarity. The family includes sulfides and oxides of tin-alkyls or -aryls, organotins salts of carboxylic acids, organotins mercaptides, and trialkyl or triaryl tin alcoholates. Certain dioctyltin mercaptides and maleate compounds have been approved for food contact use. See also Di-n-Octyltin Maleate Polymer and Di-n-Octyltin-s,s bis(isooctyl mercaptoacetate).
